Patented Mar. 1,. 1938 UNITED STATES PATENTOFFICE 2,109,507 HAIR-CLIPPING AND SHAVING DEVICE Max Salz, New York, N. Y. Application October30, 1936, Serial No. 108,421 12 Claims. (01. 30-43) This inventionrelates to razors and hair clippers of the power driven type and has forone of its objects the provision of a tonsorial device of this nature inwhich an exceedingly thin face plate is used so that a very close shavemay be had.

Another object of the invention is to provide a device of the characterreferred to in which the cutting means comprises a stationary plate, areciprocatory plate underlying the stationary plate and magnetic meansfor maintaining the said plates in close contact with each otherthroughout their entire areas.

A further object of the invention is to provide such a tonsorial devicein which the use of pressure springs is avoided.

Another object is to produce a device of the character described inwhich the maximum simplicity of construction and operation is secured.

Other objects and advantages will appear as the nature of theimprovements is better understood, the invention consistingsubstantially in the novel arrangement and co-relation of parts hereinfully described and illustrated in the accompanying drawings, whereinsimilar reference characters are used to describe corresponding partsthroughout the several views, and then finally pointed out andspecifically defined and indicated in the appended claims.

The disclosure made the basis of exemplifying the present inventiveconcept suggests a practical embodiment thereof, but the invention isnot to be restricted to the exact details of this disclosure, and thelatter, therefore, is to be understood from an illustrative, rather thana reof which, for the purpose of illustration, is shown,

in the accompanying drawings, in which:

Figure 1 is a side elevation, partly in section, of one form-of myinvention;

Figure 6 is a top plan view of the reciprocatory cutting plate;

Figure 7 is a top plan view of the stationary or face plate;

Figure 8 is a perspective view of the cap;

Figure 9 is a fragmental side view of modified form of my invention,

Figure 10 is a sectional ,view thereof taken on line iii-l0 Fig. 9, and

Figs. 11 and 12 are enlarged sectional views of the mechanism shown atthe top of Figs. 1 and 2 respectively.

Referring now to the drawings in detail, indicates the driving or motormechanism, which comprises a preferably laminated core 2| terminating atthe top thereof with a pair of poles 22 and at the opposite end with ashank 23 about which a magnetic coil 24 is wound. Passing centrallythrough the core 2| is a shaft 25 carrying at the top thereof a balanceor fly ,wheel 26. The shaft 25 is provided at the bottom thereof with anextension 21 which is elliptical in cross section and it engages amake-and-break switch 28 commonly used in this type of razor. The saidswitch is electrically connected to a plate 29 (see Fig. l) whichcarries a pair of pins or prongs 30 for engaging an electric socket (notshown) leading to an electric source of supply. The said switch is alsoelectrically connected to the magnetic coil 24 in the usual manner. Aknurled thumb wheel 3| secured to the shaft 25 and operable through anopening 32 in' an outer casing or housing 33 provides means for startingthe motor mechanism.

Secured to magnetic poles 22 by means of screws 35 is a guard plate 36having a central opening 31 through which passes a sleeve 38 upon whichthere is pivotally mounted a lever 39.' overlying the said guard plate36 and lever 39 is a cutting plate 40 having elongated slots 4i 3 alongboth side edges thereof and is further provided with a central elongatedslot 42 for the reception of an extension 43 which is eccentricallypositioned with respect to the shaft 25 for reciprocating the plate 40during a hair clipping or shaving operation.

Overlying the reciprocatory cutting plate 36 is a stationary face plate45 having outer rows of teeth 46 at its side edges and inner rows ofteeth 41 spaced inwardly from the said side edges, the dis tance fromthe top of the teeth 46 to the bottom of the teeth 41 being equal toapproximately the depth of the slots 4|. Due to the fact that the blade45 is exceedingly thin a long tooth would tend tomove or spring from itsbase; to overcome this the two rows of teeth 46 and 41 are provided.-Furthermore two such rows of shallow or short teeth provide a greatercutting area than but a single row of such teeth and the solid metalbetween the outer and inner teeth acts as a reinforcement for the outerteeth. A cap 48 is provided at the top of the device, and has pins 49 onthe inner surface thereof extending downwardly through openings 50 inthe face plate 45 and elongated openings 5| in the reciprocatory plate40 and extend into the countersunk openings 52 in the guard-plate 36which openings 52 admit the heads of the screws 35. The pins 49 havereduced portions 53 with which notches 54 on the lever 39 are adapted tolockingly engage to unite or to tie together the guard plate 36,reciprocatory plate 40, stationary plate 45 and cap 48. It is to beunderstood that the holes 50 in the stationary face plate are of thesame diameter as the body of the pins 49. The end edges 55 of the lever39 are roughened or serrated so that the said lever may be manipulatedby the thumb nail of the user.

To operate my novel tonsorial device, it is first electrically connectedto an electric source of supply by inserting the prongs 30 into anelectric socket and then turning the thumb wheel 3|. The electriccurrent which operates the motor 20 to rotate the shaft 25 and oscillateor reciprocate the plate 40 by means of the eccentric extension 43, alsoenergizes or magnetizes the poles 22 thus causing the stationary faceplate 45 to contact the reciprocatory plate 40 evenly throughout itsentire area, thus eliminating the use of pressure springs and enablingthe face plate to be made as thin as .001 of an inch and insuring a veryclose shave. t

It will be readily understood that through the use of magnetism forkeeping the plates 40 and 45 in cutting engagement, no buckling of theface plate 45 is possible as is in the case where springs are used forthis purpose, as the magnetic force acts evenly throughout the entiresurface areas of the said plates. It is also to be understood that dueto the aforesaid, magnetic use, expensive stationary face plates .orhousings are avoided, as when the face plate 45 becomes worn it canreadily be replaced. It will further be understood that instead of usingan electromagnet I may employ a permanent magnet for drawing the plates40 and 45 together.

In Figs. 9 and 10, I have shown a modified form of my invention,wherein, instead of using flat cutting plates, where the cutting area islimited to the depth of the slots 4|, I employ curved or cylindricalcutting plates. In this modified form the reciprocatory plate comprisesa solid bottom SI and a slotted upper shell 62. The bottom portion BI isprovided with a pair of slideways 63 which are in sliding engagementwith extensions 64 on the frame or handle portion 65 of the device. Theface plate 66 like the face plate 45 comprises an exceedingly thin waferwhich is magnetically held against the outer circumference of thereciprocating plate 60. The said plate 60 may be magnetized and thepoles thereof may be so positioned relatively to the poles of the magnetwithin the frame 65 as to cause same to be repelled against the outer orface plate 60. The said plate 66 is provided with cutting slots 61 whichcooperate with the slots 68 in the shell 62 for shaving or hair cutting.The slots 61 and 68 are rectangular in front elevation and are normallyin alinement one with the other, and when the plate is reciprocated ashearing action takes place at the vertical edges of the said slots. Theplate 66 is further provided with cut-outs or slots 69 which are adaptedto engage the projections B4 to maintain same stationary.

To assemble the cutting mechanism of this modified form of my invention,the face plate 66 is flexed and snapped into position so that thecutouts 69 engage, the projections 64 on the stationary frame 65 and theinner or reciprocating plate 60 is slid in from one end, after which theoperating shaft 25 is inserted into the opening 10 in the bottom of theplate 60. In this form of the invention the cutting surface extends overone half the circumference of the blades 60 and 66.

It is to be understood that in both forms of my invention the strengthof the magnet is such that While it will maintain the cutting plates ineven close contact, nevertheless it will permit of reciprocatory.movement of the lower plates.

From the foregoing it will be seen that I have provided a simple andefiicient hair cutting or shaving device wherewith an exceedingly closeshave can be had, and one in which no sharp cutting edges come in directcontact with the skin or face of the user.
